Application January 11, 1938, Serial No. 184,459 6 Claims. (01. 132-41) This invention relates to devices for treatment of the hair,.and‘ more particularly to hair curl has a. straight intermediate portion passing . through the opening l2 ‘of the roller and thereby pivotally mounting the 'roller ‘on the ball. The ' sides of the bail are sloped toward the narrow - One of the objects of the invention is to pro 5 vide a curler on which the hair my be wound portion i8 as clearly shown in the drawing. 5 and clamped with means for latching or looking 1 The roller is of greater diameter than the bore of the tube or mandreLso that only a portion the hair and curler together. Heretofore, curl ers have consisted of a tubular body or mandrel of the roller may enter the adjacent opened end on which the hair is wound, a clamp which may of said tube to effect better coaction of the sur faces H ‘with the .wall of the tube It. Said 10 10 fit over the hair, and a locking means for look ing the parts together, but this locking means mandrel II and jaw l5 ‘are preferably perforated, \ ers. has proven more or less unsatisfactory. Exist ing curlers of the type mentioned have proven unsatisfactory because in use the roller or latch 15 mg means has a round peripheral surface which does not grip or sufficiently engage the end of the mandrel to prevent slippage of the roller and clamp. These objections have been overcome and an e?icient clamping means provided by em ploying a roller or disk of polygonal form which 20 cooperates with the tubular. end of the mandrel. Such a polygonal or, to be more specific, octag onal roller readily snaps over the end of the mandrel and seats itself in position. Such an octagonal roller is further advantageous; since as at l9 and 20' respectively, to facilitate the pas sage of air through the device and hair. , In the use of my improved curler, while the jaw’ I5 is raised, the hair is wrapped about the 15 , mandrel l4 suiiiclently to anchor the hair there on, after which the jawis clamped in closed po sition and the wrapping of. the hair continued about the tube and jaw. when the wrapping is completed, the ball or clamp I1 is pressed toward 20 the free end of the mandrel and the roller is cammed over the edge of the mandrel and slipped into the adjacent open end thereof, ef-_ ,fectively clamping such bail or clamp securely and in an accurately centered position. The 25 2 U1. the various ?at surfaces and angles facilitate ridges formed by the intersection of the flat of’the roller iii tend to create su?icient engagement by ‘the ?ngers when moving the sides leverage to permit the roller to- clip or slip in roller to and from clamping position. the roller I0 is seated in the tube or‘ mandrel, _ In the drawing: 30 Figure 1 is a plan view of one form of curler ll.
